Plan HG-1785 (1,080 Sq Ft (30×36) 3 Bed, 2 Bath Barndo Floor Plan with Shop — Pull-Through Shop + Open Living) is an IRC R304/R310-vetted barndominium blueprint engineered around a 36'-0" × 30'-0" structural grid (1,080 sq ft base footprint, 0.83:1 Square-Bay Proportion). Configured on the Pull-Through Shop + Open Living topology, this layout delivers 675 sq ft of conditioned residential living area paired with a 405 sq ft fire-separated workshop/garage bay and 180 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: 1-BAY SHOP / GARAGE (13'-6" × 30'-0", 405 sq ft), PRIMARY SUITE (11'-6" × 13'-0", 150 sq ft), BEDROOM 2 (11'-0" × 13'-0", 143 sq ft), GREAT ROOM & DINING (13'-0" × 17'-0", 221 sq ft), BATH & MUDROOM (9'-6" × 7'-6", 71 sq ft), KITCHEN & ISLAND (9'-6" × 9'-6", 90 sq ft). Plumbing rough-ins are consolidated across BATH & MUDROOM, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 150 sq ft; BEDROOM 2 at 143 sq ft) are acoustically buffered from the primary living core and positioned on exterior elevations for code-compliant egress glazing.

From a builder takeoff standpoint, the 36' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 132 linear feet of 6" exterior wall framing (~164 framing studs/posts) and 114 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 1,275 sq ft of roofing material (15 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 24 cubic yards of 4,000-PSI concrete.

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-1785 (1,080 sq ft base footprint) ranges from $32,500 to $41,500 ($32/sq ft baseline).

Use the interactive Regional Cost Multiplier on this page to adjust for your local labor market and owner-builder sweat equity.

What are the exact room dimensions inside this 675 sq ft 3-bedroom layout?

Plan HG-1785 features 6 architecturally solved spaces inside its 36' × 30' footprint: 1-BAY SHOP / GARAGE (13'-6" × 30'-0", 405 sq ft), PRIMARY SUITE (11'-6" × 13'-0", 150 sq ft), BEDROOM 2 (11'-0" × 13'-0", 143 sq ft), GREAT ROOM & DINING (13'-0" × 17'-0", 221 sq ft), BATH & MUDROOM (9'-6" × 7'-6", 71 sq ft), KITCHEN & ISLAND (9'-6" × 9'-6", 90 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 36' × 30' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 36'-0" × 30'-0" structural grid (132 LF perimeter) with clear-span 4:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for Cold-Formed Steel / Post-Frame Clear-Span Trusses (8' o.c.), conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
